This final report summarizes work done to formulate and test some cognitively-based principles useful for designing instruction in scientific or engineering fields. These principles stress the coherence and interpretability of the knowledge acquired by students. The principles were specifically applied to: (1) analyze the underlying knowledge and…

ProbLab is a probability-and-statistics unit developed at the Center for Connected Learning and Computer-Based Modeling, Northwestern University. Students analyze the combinatorial space of the 9-block, a 3-by-3 grid of squares, in which each square can be either green or blue. All 512 possible 9-blocks are constructed and assembled in a "bar…

Uses computers to help students identify variables controlling pendulum period. A program written in BASIC for the Apple computer is provided. The activities are useful for developing science skills, mathematics skills, and computer skills. (PR)

Introduces microcomputer interfacing as a method for explaining and demonstrating various aspects of the concept of function. Provides three experiments with illustrations and typical computer graphic displays: pendulum motion, pendulum study using two pendulums, and heat absorption and radiation. (YP)

This document contains the second volume of the proceedings of the 30th Annual Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Mathematics at the Centre." This volume features 60 research reports by presenters with last names beginning between Abr…
